Problem

Implement bank_account_simulator(initial_balance, ops) that applies a list of ops to a BankAccount starting at initial_balance. Ops are ['deposit', amt], ['withdraw', amt], or ['balance']. Withdraw raises ValueError if amt > balance. Return the final balance after all ops; if any withdraw would overdraw, return the string 'ValueError' instead.

Summary

Deposits, withdrawals, and the risk of going negative.
